The study was conducted with the aim of determining the influence of brief immersions in aqueous solutions of sodium chloride (NaCl) and/or copper sulphate (CuSO4) on the physiological state (hematological and blood plasma biochemical indicators) of pikeperch selects (body weight 509.89 ± 99.56 g; body length 33.9 ± 2.0 cm). Immersion was conducted in a water temperature similar to that of spawning (15.1°C). The fish were divided into three experimental groups and one control group: NaCl group (NaCl concentration – 5 g l−1), CuSO4 group (CuSO4 concentration – 1.5 mg l−1), and NaCl+CuSO4 group (NaCl concentration – 5 g l−1; CuSO4 concentration – 1.5 mg l−1). Blood was drawn immediately after immersion (0 h), 24, and 48 h following the conclusion of immersion. Immediately after immersion, elevated values were noted in white and red blood cell counts, hematocrit, and hemoglobin, while mean corpuscular hemoglobin concentration values were elevated only in the NaCl group 24 and 48 h following the conclusion of immersion. Changes in blood plasma biochemical indicators were noted only immediately after the conclusion of immersion with elevated values of glucose (NaCl, CuSO4, and NaCl+CuSO4 groups), lactate (NaCl and CuSO4 groups), and ammonia, sodium, and chlorine ions (CuSO4 group). Greater aspartate aminotransferase activity was noted in the fish from the CuSO4 group immediately after immersion, while the least significant changes following immersion were noted in specimens from the NaCl+CuSO4 group.
